Fellow jammer here (I made Gravity Core). I really have to hand it to you - this is the most ambitious entry in the jam. The live-updating map pipeline is the kind of tooling trick that makes me jealous; it shows in how big and connected the world feels.

The color mechanic is the star: starting grayscale and watching the world bloom after each boss is a strong hook, and tying each color to a new power/map access is smart design. I grabbed the macOS build and it ran smoothly on Metal - though the web version really struggled on my machine (Bevy WASM with this many entities is a beast, so no judgment there; the native build is the way).

I'll echo Sampesss on the small black spiders on black background - your apology in the comments was heard, ha. A faint outline or a slightly lighter ground tone near them would fix it without hurting the look.

11 bosses and a map this size in 72 hours is just showing off. Good luck with the rest of voting!

If it really made for 3 days by 2 people its impressive.

I was play in it around 1.5 hours and i think collect all colors, for me its best submission on this jam.
It remember me Hollow Knight.
I almost rage quit after 15 fall damage dies.

10 small black spiders on black background out of 10!
